GAS-STOVE BURNER.

SPECIFICATION forming part of Letters Patent No. 575,052, dated January12, 1897.

Application filed May 22, 1896. Serial No. 592,525. (No model.) I

lb all whom it may concern:

Be it known that I, ALFRED E. DETVVILER, of Chicago, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Gas-Stove Burners; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it pertains to makeand use the same, reference being had to the accompanying drawings, andto the letters of reference marked thereon, which form a part of thisspecification.

The main object of my invention is to facilitate the lighting andregulation of burners which are inclosed or not exposed to view or arenot easily accessible.

It consists, essentially, of a burner having one or more gas-dischargeapertures, or series of apertures, extending from the inside to theoutside of the stove, that portion of the apertures outside serving tolight the burner, a gas and air supply connection tapping the burner ata point removed from its lighting extension, and a cut-off controllingthe supply of gas to said extension.

In the accompanying drawings like letters designate the same parts inboth figures.

Figure lis a plan view of a burner to which my improvement is applied;and Fig. 2 is a perspective view of another form of burner, showing amodification of my improved lighting and regulating device.

Referring to Fig. 1, illustrating a form of burner now in common use,consisting of a shallow-chambered casting A with gas-discharge aperturesin the upper or under side, B designates a lighting and regulatingextension formed with or applied thereto and projecting through the wall0 of the stove-casing. It is formed with an aperture, or series ofapertures, extending from the outside to the inside of the casing incommunication with or in proximity to the apertures in the body of theburner, so that when the gas issuing from the apertures in the extensionis lighted it will communicate its flame through an opening inthecasing, as shown in Fig. 2, to the gas issuing from the aperturesinside, and thus light the concealed part of the burner within thestove. D designates a plug loosely fitted inside of the extension 13 andadapted, when thrust into the same, to close the aperture or aperturestherein outside of the casing.

Referring to Fig. 2, the lighting extension B of the burner outside ofthe casing O is provided with a rotary tubular plug or valve D, whichhas a longitudinal slot cl in one side, which may be turned into and outof range with the gas-discharge aperture or apertures in said extension,so as to control the supply of gas thereto without affecting the supplyto the apertures of the burner inside the casing.

The apertures in the lighting extension of both forms of the burnercorresponding in size or area with those inside, the size, condition, orquality of the flame within the stove may be determined from thatoutside of the casing, so that said extension not only affords means forlighting the concealed and inaccessible portion of the burner, but alsofor determining the condition of the flame for the purpose ofregulation, which is accomplished in the usual way by a cook or valve 6in the gas-supply pipe of the stove.

E designates the gas and air supply connection and mixing-chamber of theburner, which taps the same at a point removed from its lightingextension, so that the position of the valve or cut-off in the lightingextension will not affect the supply of gas to the body or main portionof the burner Within the easmg.

I do not wish to be understood as limiting myself to the exact detailsherein shown and described, as they may be variously modified within thespirit and intended scope of my invention; as, for instance, the form ofthe burner and the construction and arrangement lating connection, aswellas the construction and arrangement of the cut-off controlling thesupply of gas to the lighting extension, may be modified in various wayswithout materially affecting the operation of the device.

I claim-- I 1. The combination with the casing of a stove, of a burnerhaving a gas and air sup ply connection and one or more gas-dischargeapertures inside of said casing, and provided with a lighting extensionprojecting outside of its gas and an supply, mixing and regu of saidcasing, and having one or more gasdischarge apertures in communicationwith or proximity to the apertures of the burner inside of the casingwhich has an opening for the connnunication of flame from the aperturesoutside to those inside, and a valve or cut-ofi? controlling the supplyof gas to said lighting extension, substantially as and for the purposesset forth.

2. The combination With the fire-chamber of a stove, of a burner-pipelocated Within the fire-chamber, extending outside the stove, andprovided with a series of apertures extending therealong from the insideto the outside of the fire-chamber, said fire-chamberhaving an openingadjacent to the series of apertures and the apertures outside of thefirechamber serving as lighting apertures, and devices for supplying andmixing air and gas, tapping the said burner-pipe at a point removed fromthe lighting apertures, substantially as and for the purposes set forth.

3. In a gas-stove, a burner provided with gas-supplyingand air-mixingdevices, and an extension projectiugoutside of the stove, and providedwith a series of lighting-apertures, and a valve located in saidextension, sub stantially as and for the purposes set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two Witnesses.

ALFRED E. DETWILER.
